Windows + Doors
Passive house is a construction concept that promotes energy efficiency as a means to have a more comfortable, ecological, and affordable building. By combining climate-specific design and energy-efficient building materials and products, construction using the passive house framework can produce savings of up to 90% on heating and cooling bills when compared to regular stick-built structures.
PHIUS (Passive House Institute US, Inc.) is the leading non-profit organization that certifies builds, maintains build standards, undertakes new research into energy efficient building processes, and trains professionals to become certifiers.

The below tables show total window performance using the following measurements:
This represents the heat flow rate through a window expressed in W/m²·K (SI units) or BTU/hr·ft²·°F (IP units). The lower the number, the better the window system is at reducing heat loss.
The amount of solar radiation that enters a building as heat. The lower the number, the better the glazing is at preventing solar gain.
